Application filed November 14, 1921. Serial No; 515,050.

To all whom it may concern:

v/Be it'known that I, DAVID4 GRANT, al citin Zen of the United States, residing at Chi# cago, in the lcountyof Cookand State of Illinois, have invented new and useful Improvements in Arch Supports, of which the following is a specification.

This invention relates to varch supports and an object of the invention is to provide an arch support which is constructed of resilient sheet metal and is designed to fit the foot of a user and to embody the proper degree of flexibility Vand resiliency to cause it yto properly conform to the arch of the foot and to givea spring actionin walking, as well as to correct the evil effect of improperly braced or supported arches.

Other objects of the inventionA will appear in the following detailed description taken in connection with the accompanying drawing wherein:y

Fig. 1 is a top plan of the improved arch support.

Fig. 2 is a longitudinal section on the line 2 2 of Fig. 1 showing the arch support in its normal position.

Fig. 3 is a section similar to Fig. 2, showing the arch support under pressure.

Fig. 4 is a plan of the resilient spring of the drawings to engage the arch and brace plate.

Fig. 5 is a side elevation of the resilient spring plate, showing the position it assumes when weight is applied thereto, in dotted lines. y,

Fig. 6 is a det-ail section 6-6 of Fig. 1.

Referring more particularly to the drawtaken on the line ings, illustrating one of the many construetions of the improved arch plate, the numeral 1 indicates the base plate which is constructed of suitable sheet metal and is shaped to conform to the interior of va shoe. The base plate 1 is provided with spaced slots 2 and 3 which extend at an angle to each other.

and open into the recesses 1 formed beneath the base plate by means of the clips or retaining members 5. The members l 5 are riveted or otherwise suitably attached to the base plate 1, as clearly shownrat 6 in Figs. 2 and 3 of the drawings. The retaining members 5 are provided with substantially semicircular extensions 5 on their forward edges which fit into substantially semicircular recesses 5a in the tongues 7 and 8' to permit a limited rocking movement of the spring plate 9. The openings or slots 2 and 33 are provided for receiving therethrough the tongues7 and 8 which are formed/upon the resilient spring plate 9. .The plate ,95.v formed of suitable spring metal andthel` tongues 7 and 8 project from its side edges directly opposite each other as clearly shown in Fig. kt of the drawings, whilethe plate 9- is provided with slots or recesses 10 extending thereinto at each end of the tongues 7 and 8 providing vrelatively short tongues or y free edge portions 11 which lie flat against the upper surfaces o-f the base plate '1 outwardly of the openings 2 and 3 as clearlyl shown in Fig. 6 of the drawings forming a further support for the spring plate 9.

As clearly shown in Figs. 2, 3 and 6 of the drawings, the upper surfaces of the tongues 7 4and 8 abut against the undersurface of the plate 1 providing relativelyv great l bearingl surface between the tongues and:

base plate andv permitting yielding 'resilient movement of the plate 9 as well as .permitting limited oscillatory movement of the plate, which Avarious movements are pro-y vided to accommodate movements of the foot during walking. The spring plate 9 is arched yto conform to the arch of the foot of the wearer and its curved sides 12 and 15 curve upwardly as clearly shown in Fig. 5

er, which will yield under pressure into the positions shown in Fig. 3 of the drawings and in dotted lines in Fig. 5 maintaining support for the arch at all times and distributing the weight of the body of the wearer from the arch upon the ball of the foot and heel of the wearer. While in the drawings bothside edges of the spring plate or arch 9 are shown curved, it is to be understood that only one side edge may be provided witha curved portion 12 or 15 as desired without departing from the spirit of this invention. The metal plates 1 and 9 of the arch support may be covered by Itop and .bottom layers '13 and 14 respectively,

of leather or analogous material. As shown in the drawings, the bottom layer 14C is substantially of the same thickness as the members V5 and is provided with cut out portions invention may be constructed in other manners and the parts associated in other relations and, therefore, I do not desire to be limited in any manner except as set forth in the claim hereunto appended.

Having thus described my invention What I claim is:

An arch support comprising a base plate having spaced slots, a resilient spring plate having tongues on its end edges and provided With recesses extending into the spring plate at each side of said tongues, said tongues being adapted to be inserted through Lesaese said slots to separably connect the resilient spring plate to the base plate, said recesses forming relatively short tongues at Veach side of said first named tongues which engage against the upper surfaces of the base plateyvhen said first named tongues are inserted through said openings, and pocket forming members attached to said base plate and forming pockets for receiving said first named tongues.`

In testimony whereof I aix my signature.
